Hi,

 

I recently changed the 9W7 Bluetooth Module + Bolero HU to a VW RCD340G Plus.

 

Positives - Perfect Fitment. No mods required 

Overall Connectivity is very good.

 

Negatives -

 

The audio quality has dropped drastically.

 

Possible reasons -

 

Not enough output power in the RCD340G Plus as the Bolero. 
 

2 Possible solutions- 

 

OEM Amplifier - 3T0035456

Active Subwoofer.

What do the experts here think?

I am not pretty sure if 3T0035456 will work with RCD340G plus. Additionally, it requires quite a lot of cabling work as each speaker is connected to the amplifier separately. I believe I have a third solution for you - use external booster amplifier pioneer gm-d1004. I have tested it and it works really great.

Also, how would a 4 channel amp work for an 8 speaker setup?

You have 8 speakers but each two of them in every door are powered from one channel.

You must make custom pass-through adapter.
